last, but not least, I've created a 100 LOC utility that lets you opt out Babel class transformation, using object literals to define actually native ES2015 classes. The reason is here, while the utility is on GitHub.

Am I forgetting anything? Oh yes, I've soldered together a Raspberry Pi Zero and a WaveShare 3.5" Touch Screen LCD, booting Web Kiosk in seconds, for a device that could be sold with the size of an i-clip and with battery and wifi included for like $35, but nobody gave a damn heck about it so my Kickstarter won't even be proposed.
P.S. I am using Medium more and more, follow me there too (at least until Medium lasts)
